Thats a good question. I can honestly say that I do not fear death. And that is not because I believe in some sort of eternal salvation, or anything like that. I believe in "real" death.

I am perfectly comfortable with my own mortality. By this, I do not mean in any sense that I am depressed, or that I "want" to die. I mean, I like my life, and hope to live for another long time yet, and as such, I will always struggle to stay alive, not out of fear of death, but out of a love for life.

But I guess the real thing to bear in mind, is that you cannot do anything about it. You are going to die, end of story, so why worry about it? (Very flippant attitude, I know).
But, also, you have to ask, what it is you fear? Perhaps you find the thought of non-existence scary...but don't worry about that...you won't be around to experience it!

I guess I can't really put it into words, but an acceptance of your own mortality will come in time.

Anyway, to get back on topic, I think lordjeebus, is pretty much on target.
You can only really "measure" time based on previous experiences.

I also find it likely that the fact that children form memories faster than adults plays a large role. Children are more attentive than adults. They are drawing in more information from the world around them. As such, more seems to happen, in a short space of time.
Both of these, coupled with the hypothesis that consciousness and memory are inextricably linked, would go very far to explaining a lot.
